First use flow-delay membrane for pourable containerized motor oils and other viscous fluids

ABSTRACT

The present invention is a flexible disc-like membrane that is burstable on demand. The membrane is adapted to accommodate an accommodating container (approximately 32 fl. oz.) for automotive type motor oils and other viscous fluids. The membrane serves to contain a fluid content within a container at first use, while the container (with cap removed) is being positioned for pouring and until the consumer manually initiates the membrane to burst so as to release the contained fluid into an engine or other equipment. The present invention improves container content pour-ability by allowing the consumer to manually initiate the release of a fluid content to a free-flowing action at the proper time as to avoid fluid content spillage without the need for the use of a funnel or other pouring assistance.

BACKGROUND OF THE INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to common containers (approximately1 U.S. quart—32 fl. oz.) for automotive type motor oils and otherviscous fluids where a burstable membrane is adapted to accommodate anaccommodating container to postpone the first use free-flowing action ofa containerized fluid in a manner that avoids fluid content spillagewhen pouring the fluid content into an engine or other equipment.

[0003] 2. Description of Prior Art

[0004] The current use of high density polyethylene (plastic)rectangularly shaped containers (approximately 32 fl. oz.) for motor oiland like fluids with an offset or centrally located tubular spout and acircular spout opening has improved ease of pour-ability for consumerusage to some degree over former use of cylindrical composite fibercontainers that had no spout or spout opening. The invention of(Doering, U.S. Pat. No. 4,877,142) discloses a polyethylene rectangularcontainer (approximately 32 fl. oz.) for motor oil with an offsettubular spout, as does the design of (Kearse et al., U.S. Pat. No.D352,904) and the design of (Bridger et al., U.S. Pat. No. D337,946).The disclosure of (Frazer, U.S. Pat. No. D314,509) includes asubstantially rectangular container with a centrally oriented tubularspout. These containers all have provided some improvement tocontainerized fluid pour-ability but there is still a need for furtherimprovement, especially at first use when the container is at maximumfullness of content. The prior art rectangular containers mentioned andothers still lend themselves to content spillage at the beginning ofpouring action because when rotating a container (with the usual capremoved) from the normal position (spout opening upward) to the invertedposition for pouring (spout opening downward) there is an uncontrolledoutward surge of the container content before the opening end of thecontainer spout can be placed fully within the oil fill or other fluidfill opening of an engine or other equipment. Some of the prior artcontainers are particularly designed with offset and/or angular spoutsto allow pouring to begin by rotating a container from the normalposition (spout opening upward) to the horizontal position for pouring(spout horizontal) to align the opening end of the container spout withthe engine oil or other fluid fill opening, thereby allowing a sloweremptying of the container content to reduce uncontrolled content surgeand reduce content spillage. These containers remain vulnerable to firstuse content spillage at the beginning of pouring, partially because ofthe containers' fullness of content and partially because ofobstructions encountered on the engine or other equipment (hoses, belts,brackets, etc.). Most engines have fluid fill intake openings that areless than accessible to positioning a container fully in a pouringposition (inverted or horizontal) to begin pouring before contentspillage can occur. In most cases only after a portion of the containercontents have been emptied can the container be handled with relativeease, as when the contents of a container are only partially emptied atthe first use application, i.e. the pouring action of a containercontent is stopped before emptying all of the content at the first useapplication, at some later time the pouring action is re-started withthe unused content of the container for a second application withminimal chance of content spillage for the second application. Thereforeit is still the first use of the individual container that is mostlikely to cause content spillage without the use of a funnel or otherpouring assistance.

[0005] The invention of (Maguire, et al., U.S. Pat. No. 5,419,467)discloses a two-piece on/off pouring spout able to be coupled to sometypes of common containers for motor oil or like fluids. This prior artis relatively inexpensive and improves container content pour-ability byallowing the container to be inverted before the content flow isreleased, but this invention has to be continually coupled andun-coupled from one container to another, i.e. the average automotiveengine oil change usually requires 3 to 5 separate (32 fl. oz.) oilcontainers. In addition, this invention as with funnels or other pouringassistance devices will retain an oily film which has to be continuallycleaned of product oil or like fluid and further has to be continuallycleaned of dust, and foreign particles that tend to settle an oilysurfaces.

[0006] In the case of small engines such as lawn mowers or otherequipment where the oil fill intake opening is smaller than the average32 fl. oz. container spout opening and where such equipment requiresonly one or less than one 32 fl. oz. container of oil to fill theequipment, the present inventions' primary use (first use delay of fluidcontent free-flow) may be by-passed if desired. Puncturing(popping-open) the flow delay membrane (of an accommodating container)inwardly with thumb or forefinger after the container cap removal andbefore positioning the container for pouring will allow the container tobe used in the conventional manner, using a funnel or some form ofpouring assistance to guide the uncontrolled content surge when pouringthe fluid content. Even when the primary use of the flow delay membraneis occasionally by-passed, the present invention serves a secondaryfunction by replacing and serving as the usual seal for the containerwhen the container is originally filled, sealed and capped. However mostoil and related fluid container manufacturers now produce containersizes specifically for small engines such as a 20 fl. oz. container forlawn mowers and like equipment.

[0007] The intended consumer usage of the present invention isautomotive and industrial by improving containerized oil and relatedfluid pour-ability, but other uses may apply. The present invention canbe manufactured and applied inexpensively enough to be used once andthen discarded with the accommodating container when emptied. Most motoroil and like fluid containers are emptied at first use, i.e. the averageautomotive engine crankcase capacity for oil fill is from 3 to 5 U.S.quarts (96 fl. oz. to 160 fl. oz.), thus in the case of a 4½ U.S. quart(144 fl. oz.) capacity engine oil fill, 4 individual 1 U.S. quart (32fl. oz.) accommodating containers would be emptied at first use and a5^(th) 1 U.S. quart (32 fl. oz.) accommodating container is onlypartially emptied at the first use. In this case the consumertemporarily recaps the partially emptied 5^(th) container until the nextuse. The 5^(th) partially emptied container can later be un-capped andthen completely emptied with far less chance of content spillage duringa second use because of the previously removed quantity of oil at thefirst use of the 5^(th) container even though the flow delay membrane ofthe 5^(th) container was ruptured at the first use of the 5^(th)container.

SUMMARY OF THE INVENTION

[0008] The present invention is a first use flow delay membrane topostpone the first use free-flowing action of a pourable viscous fluid(motor oil and other fluids) from an accommodating container(approximately 1 U.S. quart—32 fl. oz.), until such container can beproperly positioned for pouring as to avoid fluid content spillagewithout the need for the use of a funnel or other pouring assistancedevice. The flow delay membrane serves as a temporary diaphragm byblocking the container content free-flow while the consumer inverts thecontainer (positions the container spout opening end downward) and untilthe consumer can place the container spout opening end fully within theoil fill or other fluid fill intake opening of an engine or otherequipment, allowing the consumer to initiate, on demand, the rupture ofthe membrane, thereby allowing the free-flow action of the fluid contentto begin after the accommodating container is properly positioned forpouring.

[0009] The flow delay membrane is a flexible, circular, disc-likemembrane that includes radial grooves and diametric grooves and furtherincludes separation seams along the diametric grooves for the membraneto be ruptureable (burstable) on demand. The present invention isdiametrically dimensioned to accommodate the variant spout openingdiameters of random variable types of containers (usually but notlimited to 32 fl. oz.). A fluid filled and cap sealed accommodatingcontainer having the flow delay membrane in place is opened (containercap removed), thereby exposing the top side of the flow delay membraneintact, the container is then properly positioned for pouring. Theconsumer can, at this point, manually compress (squeeze) the containerto pressurize the fluid content within the accommodating container,which in turn pressurizes the inside (bottom side) of the flow delaymembrane causing the membrane to yield (rupture) radially outward fromthe diametric center of the membrane along the separation seams, thusreleasing the gravity free-flow of the previously restricted containerfluid content directly into the fluid fill opening of an engine or otherequipment, thereby avoiding undesired content spillage and eliminatingthe need for the use of a funnel or other pouring assistance device.

[0010] The present invention is sufficiently inexpensive to be used onceand then disposed of along with the accommodating container whenemptied; can replace the usual seal (leak seal) of the accommodatingcontainer; and further does not interfere with the usual capping (capclosure) material or process of the accommodating container. Accordinglyseveral objects and advantages of the present invention are to provide:

[0011] (a) A flow delay membrane that is adapted to the usual spoutopening end rim of a motor oil or other viscous fluid common container.

[0012] (b) A flow delay membrane that can replace some types of usualseals (plastic or composite fiber) that are sometimes placed snugglywithin and flush to the inside top of the usual cap of the container,and a flow delay membrane that can replace other types of usual seals(plastic, composite fiber, or metallic foil) that are sometimes affixedto the container usual spout opening end rim (for sealing only) at thetime of the container filling and capping process.

[0013] (c) A flow delay membrane that can be incorporated into a commoncontainer for motor oil or other viscous fluids at the time of thecontainer filling without changing the usual filling, sealing andcapping process that the fluid filling manufacture uses to originallyfill, seal and cap the container.

[0014] (d) A flow delay membrane that serves to avoid content spillagewhen pouring a fluid content, and a flow delay membrane that eliminatesthe need for the use of a funneling (flow guiding) device or othersupplementary pouring assistance when pouring a fluid content.

[0015] (e) A flow delay membrane that improves pour-ability of acontained viscous fluid from an accommodating container at first use bydelaying the natural free-flowing action of the contained fluid until,(with the usual cap removed) the container can be rotatively inverted(spout opening end positioned downward) and until the container can bemaneuvered to having the container spout opening end being placed fullywithin the fluid fill opening of an engine or other equipment.

[0016] (f) A flow delay membrane whereby the consumer can manuallyinitiate the free-flowing action of the contained fluid from anaccommodating container, at the consumer's readiness, directly into thefluid fill opening of an engine or other equipment.

[0017] (g) A flow delay membrane that can be manufactured and appliedcheaply enough to be discarded along with the accommodating containeronce the container contents have been emptied.

[0018] (h) A flow delay membrane that allows the normal air flow into anaccommodating container where the normal airflow helps to facilitate acontainer content free-flow normally from a common container, hencenormal air flow being allowed into the accommodating container by way ofthe open flow delay membrane once the accommodating container has beenpositioned for pouring and the flow delay membrane has been ruptured,and a flow delay membrane that can be by-passed (if occasionallydesired) by punching through the membrane with thumb or forefingerbefore positioning the accommodating container for pouring to enable theuse of the accommodating container in the conventional manner byemploying a supplementary pouring assistance device.

[0019] A further object and advantage of the present invention is toprovide a flow delay membrane that becomes secured against the insidetop of the usual cap of an accommodating container by the usual cappingof the accommodating container when the fluid filling manufacturerfactory seals (caps) the container, whereby the flow delay membranecannot be accidentally or intentionally ruptured before the factoryemplaced cap is removed by the consumer. These and other objects andadvantages will become apparent from the detailed description anddrawings, which follow.

DETAILED DESCRIPTION OF THE INVENTION

[0030] As illustrated and described by the drawings and other referencethe present invention is a substantially flat disc-like diaphragmaticmembrane 10. Membrane 10 is flexible and is adapted to accommodate anaccommodating container 12. Container 12 having an approximate capacityof one U.S. quart (32 fl. oz.) for containing motor oil or other fluids.Membrane 10 is accommodated at the end of a threaded tubular spout 14 ofcontainer 12 (FIGS. 1 and 3). More specifically, membrane 10 ispermeated to a circular rim 16 of spout 14 where rim 16 defines andsurrounds a circular opening 18 which is the fill or discharge openingat spout 14 of container 12 (FIGS. 1 and 3). Container 12 is normallypositioned for filling, transport and storage with opening 18 of spout14 facing upward and where opening 18 is normally regarded as the top ofthe container. Container 12 is normally comprised of plastic(polyethylene) and is usually rectangular in shape. Membrane 10 iscomprised of a synthetic latex rubber or rubber-like material that iscompatible with common automotive fluids such as motor oil and relatedfluids and is compatible with container 12 (the accommodating container)to which membrane 10 is to be accommodated. An average size for apreferred embodiment of the present invention is approximately {fraction(15/16)} inches in diameter and approximately {fraction (3/64)} inchesin thickness (major portion thickness), but not limited to thesedimensions. The true diameter, thickness and relative shape of thepresent invention is dictated by the variable spout opening end sizesand spout opening end shapes of the many diverse types of containers(approximately 32 fl. oz.) to which the present invention is to beadapted.

[0031] Molded into and defining the topside of membrane 10 is aplurality of diametric grooves 20 (preferred embodiment) along aplurality of axes of membrane 10 where grooves 20 intersect each otherat the diametric center of membrane 10. For illustration purposes,grooves 20 are shown along the X-axis and the Y-axis of the preferredembodiment of membrane 10 (FIGS. 5 and 6) with grooves 20 continuing themajor portion diameter of membrane 10 (FIGS. 1, 3, 5, 6, 8A, 8B and 9).From the diametric center of membrane 10, grooves 20 are in a radiateform extending outwardly and are V-shaped in cross section in thepreferred embodiment but not limited to this form or shape. The depth ofgrooves 20 is through the major portion thickness of membrane 10 forminga plurality of separation seams 22 along and relative to grooves 20,with seams 22 being the remaining portion thickness of membrane 10 alonggrooves 20. The preferred V-shape (in cross section) of grooves 20serves to create a clean straight debris free separation along thelongitudinal centers of grooves 20 at seams 22 when membrane 10 isruptured (popped-open). Grooves 20 and seams 22 shown in (FIGS. 1, 2, 5,6, 7, 8A, 8B and 9). Seams 22 shown intact (FIGS. 1, 2, 5, 6, 7, and 8A)and shown separated (FIGS. 4, 8B and 9). In combination with grooves 20there is molded into membrane 10 a plurality of radial grooves 24(U-shape in cross section) in communication with grooves 20 (FIGS. 1, 2,5, 6, 8A, 8B and 9) which forms and defines a plurality of symmetricallyradiate and substantially triangular pop-open flaps 26 (flaps 26 shownin all FIGS.). The preferred U-shape of grooves 24 serves to define andfacilitate of plurality of bending bases 28, one base 28 at each flap 26of membrane 10. Bases 28 at flaps 26 of membrane 10 where membrane 10 isshown ruptured (popped-open), shown in (FIGS. 8B and 9). Bases 28 atflaps 26 of membrane 10 where membrane 10 is shown intact, shown in(FIGS. 1 and 8A). Grooves 20 communicating with grooves 24, in additionto defining flaps 26, serve to form and define a circumference ring edge30 including and encircling membrane 10 (ring edge 30 shown in allFIGS.). The depth of grooves 24 is shallow leaving the major portionthickness of membrane 10 at base 28 (FIGS. 8A and 8B) to insure thatflaps 26 do not separate from ring edge 30 at base 28 when membrane 10is ruptured, membrane 10 shown ruptured (FIGS. 8B and 9).

[0032] Membrane 10 is adapted to accommodate an accommodating container,(after the container has been normally filled with a fluid) bypermeating ring edge 30 of membrane 10 flush to rim 16 at spout 14 ofcontainer 12 thereby sealing opening 18 of the container spout andallowing the normal capping (process and material) of container 12(filling and capping not shown). Membrane 10 (FIGS. 1 and 3) is shown inthe projected attaching position to container 12, the attached positionof membrane 10 to container 12 is shown in (FIG. 4) with membrane 10ruptured. A threaded usual cap 32 (FIG. 3), when threadedly mated tospout 14 there provides compression to the accommodated membrane(membrane 10) at a top-side 42 of membrane 10 (top-side 42 shown allFIGS.) further sealing container 12 and thereby preventing membrane 10from being ruptured before cap 32 is removed by the consumer, (cap 32,not shown mated to spout 14). Membrane 10 can serve as and replace athin wafer-like usual seal 34 (FIG. 3). Seal 34 in some applications isa plastic or composite fiber material that is placed snuggly inside cap32 before container 12 is capped. In other applications seal 34 is aplastic, composite fiber, or metallic foil material that is affixed torim 16 at spout 14 of container 12 before container 12 is capped. Bothapplications of seal 34 are for sealing only, (applications of seal 34not shown).

[0033] Upon removing cap 32 from the accommodating container, membrane10 serves to delay the gravity free-flow of the container fluid content(content not shown) while the accommodating container is being invertedand maneuvered to having the opening end (opening 18) of spout 14 fullywithin a fluid fill usual opening 36 of an engine or other equipment,which is the proper pouring position for the pouring action of thecontainer fluid content to begin conveniently (FIG. 4 opening 36 inphantom outline). Once the container is maneuvered fully into a properpouring position, the consumer can then manually initiate membrane 10 torupture thereby releasing the free-flow of the container content (FIG. 4shows membrane 10 as ruptured, free-flow of container content notshown). Content spillage from a common container (without membrane 10)occurs mostly at first use when the container is at peak fullness andwhile the container is being maneuvered and is usually encounteringobstacles on the engine or other equipment, i.e. hoses, belts, bracketsetc. (content spillage and obstacles not shown).

[0034] The present invention prevents the gravity free-flow of thecontainer fluid content while container 12 is being inverted andmaneuvered fully into a proper pouring position until, at the consumers'readiness, container 12 is manually compressed (squeezed) by a consumerhand 38 (FIG. 4) to initiate the rupture of membrane 10 thereby allowingthe container fluid content free-flow to begin (container contentfree-flow not shown). Manually compressing (squeezing) container 12pressurizes the container fluid content (content not shown) therebytransferring pressure to a bottom-side 46 of membrane 10 (bottom-side 46shown all FIGS.) causing the membrane to rupture at and along seams 22,whereby flaps 26 of membrane 10 pop-open radially outward from thediametric center of membrane 10, membrane 10 shown popped-open (FIGS. 4,8B and 9). The outward pop-open action of flaps 26 causes grooves 24 toclose, in cross section (FIG. 8B), and in turn assists in the radialbending action of flaps 26 at bases 28 further allowing the outwardswing travel of flaps 26 within membrane 10 when the membrane isruptured (FIG. 8B). Once container 12 is properly positioned for pouringand membrane 10 is ruptured (popped-open), membrane 10 then releases thefluid content of container 12 to a gravity free-flowing action (contentfree-flow not shown) for complete or partial emptying of container 12 atthe first use of the accommodating container. In the case of partialemptying of the accommodating container at the first use, container 12can be inversely positioned from the pouring position (the spout openingend downward) back to the normal position (the spout opening end upward)to end the first use before complete emptying of container 12 with farless chance of content spillage because of reduced content at the end ofthe first use, and container 12 can be later re-used at a second orfurther use with less chance of content spillage at the second usebecause of reduced content within container 12 at the start of thesecond use even though membrane 10 was previously ruptured at the startof the first use of container 12 (emptying of container 12 not shown).

[0035] Membrane 10 of the accommodating container can be manuallyby-passed, (after the usual cap removal of the accommodating container)where the consumer manually and inwardly punches-open membrane 10 ofcontainer 12, using thumb, forefinger or other object to enable the useof the accommodating container conventionally without membrane 10 intactat the first use of container 12, if occasionally desired,(punching-open membrane 10 of container 12 not shown). Membrane 10cannot be prematurely ruptured through inadvertently or intentionallycompressing the accommodating container (manually or otherwise) as longas the factory emplaced cap 32 remains threadedly mated to spout 14 ofcontainer 12, since an inside top area 40 (FIG. 3) of cap 32 normallycompresses against a top-side 42 (FIG. 3) of membrane 10 when cap 32 isthreadedly mated to spout 14 of the accommodating container therebypreventing the untimely rupture of membrane 10 (cap 32 not shown matedto spout 14 of the accommodating container).

[0036] The normal airflow into the spout opening of any of the commoncontainers mentioned and others assist in allowing the outward naturalfree-flow of the fluid content from a common container when thecontainer usual cap is removed and the container is inverted (inward airflow and outward content free-flow not shown). When container 12 withmembrane 10 in place and intact is inverted; properly positioned forpouring; and membrane 10 is manually initiated to rupture, membrane 10then allows the normal air flow into container 12 through a plurality ofvertexial areas 44 formed by flaps 26 of membrane 10 when ruptured(FIGS. 4, 8B and 9) to assist in the outward natural free-flow action ofthe accommodating container fluid content when pouring (air flow andfluid content free-flow not shown).

[0037] Now having described a preferred embodiment of the presentinvention this description should not be construed as limiting the scopeof the invention but as illustrations of the preferred embodiment, forexample, the V-shaped grooves and the U-shaped grooves (in crosssection) of the flow delay membrane may be of different shapes ordepths; the flow delay membrane may be composed of other material; thepop-open flaps of the flow delay membrane may be of other or uncommonshapes without departing from the intended purpose and scope of thepresent invention. Therefore the spirit and scope of the inventionshould be limited only by the appended claims and their legallimitations rather than by the illustrations and descriptions given.
